Abstract
A method of transporting asynchronous transfer mode cells and time-division multiplexed information over a common fiber ring includes receiving a plurality of incoming signals comprising asynchronous transfer mode cells, legacy data, or time-division multiplexed information, formatting the plurality of incoming signals into a first plurality of incoming transport signals comprising asynchronous transfer mode cells and a second plurality of incoming transport signals comprising time-division multiplexed information, constructing from the first plurality of incoming transport signals a first outgoing synchronous transfer mode signal comprising at least one asynchronous transfer mode cell, constructing from the second plurality of incoming transport signals a second outgoing synchronous transfer mode signal comprising time-division multiplexed information, and transmitting the first and second outgoing synchronous transfer mode signals over a common fiber ring.
